nptl: fix libc sigaction signal checking
We should not check for SIGCANCEL in __libc_sigaction because nptl calls this
function to setup this signal. Nptl provides it's own override for sigaction
that checks that the user cannot override signals nptl uses internally.
Linuxthreads does not use SIGCANCEL at all so this affects nptl only.
